1. How did you choose the proposed course and institute?*The way the proposed study can help me develop my skills in economics is the main reason for choosing this course. As a junior economist at the Center for Budget Policy, knowledge of public economics and knowledge of public policies are vital to analyze and formulate various budget policies and economic policies. My main studies are in economic policy, political economy and taxation, so I hope that the proposed study will improve my understanding in making good policies, from an economic perspective. Australia is a comfortable place to live and study as it is a successful multicultural country, where students from different countries can study in a safe and friendly atmosphere. Based on my research on Australian universities, the University of Queensland and the University of Adelaide are the two top universities in economic and public policy studies. The quality reputation of these two universities is strengthened by international rankings and affiliations, including the Australian Group of Eight (Go8).2. How will the proposed study contribute to your career?*I believe that my proposed study will improve my skills in academic, practical and personal experience which are useful for developing my career in the future. Firstly, the proposed study will help improve my knowledge of economic theory and its application in the public sector. Furthermore, it can improve my economic analysis skills on revenue policy, especially tax and customs revenue. Becoming an expert in public economics and public policy is my goal. Second, the proposed study can provide econometric expertise to support my task of evaluating and analyzing revenue policies. Also, using the…half of the paper…in the future. By doing so, I can provide a better policy recommendation. • Predict the impact of fiscal policy on tax and customs revenues. With each different tax policy, different outcomes will occur. By predicting the impact, we can simulate the outcomes of policy implementation. • Design an alternative policy to optimize tax revenues. Tax revenues in Indonesia are still far from optimal, so alternative strategies can be used to explore the new potential of taxation to increase tax revenues.b. Possible constraints that I think can prevent are: • Limitations of experience and knowledge in performing such tasks. • Data limitations in research. The FPA has very limited tax data, due to data privacy issues and bureaucratic issues that hinder data sharing by DG Taxation and DG Customs.
